Michigan adopted a revised Lead and Copper Rule in June of 2018. It is a notable rule because it is the only Lead and Copper Rule in the country that puts all water utilities on a path to fully replace all lead service lines within the next 20 years. But there is a lot more going on in this rule that will improve the way public water supplies manage their water systems, improve the water quality and infrastructure data they collect, and provide more complete and timely information about the risks of lead in drinking water.
